This year’s public data file is now available, featuring over 156 million metadata records deposited with Crossref through the end of April 2024 from over 19,000 members. A full breakdown of Crossref metadata statistics is available here.
For those who are using the annual data file, we’re pleased this week to release an experimental indexing tool that can help you to use the file: https://gitlab.com/crossref/labs/labs-data-file-api
This tool can create an index of the DOIs in the annual data file and then tell you where to find the record of a particular DOI in seconds, rather than having to iterate over the entire file, which can take hours. If you don’t want to create the index yourself (which, again, takes about 6 hours), there’s a torrent available here: https://academictorrents.com/details/674d3fbbca65c46c0ba52a65658aef0c8fc99e86
